Triphosgene

Triphosgene (bis(trichloromethyl) carbonate) is a white to off-white crystalline solid at room temperature, with a pungent, chloroform-like odor and moderate volatility. It melts at approximately 78–81 °C and decomposes before boiling. Classified as a carbonyl chloride derivative and reactive organic intermediate, it serves as a safer, solid alternative to phosgene in controlled chemical syntheses. Its primary industrial use is as a reagent for introducing carbonyl chloride (–COCl) functionality, enabling the production of isocyanates, carbamates, carbonates, and heterocycles. It is widely employed in the synthesis of pharmaceuticals, agrochemicals, and high-performance polymers—including polyurethanes and polycarbonates—where precise stoichiometry and handling safety are critical.
